T0 all whom, it may concern:

Be it known that I, FRED W. CooLEY, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Fireproof Grain-Elevators and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others .skilled` in the art to which it appertains to make andv use the same.

My present invention relates to the construction of elevators or grain-storage buildings and bins, and is in the nature ot' an improvement on certain of the features of construction set forth in my prior application, Serial No. 47,541, filed February 16, 1901, entitled Fireproof grain-elevators.

The invention is illustrated in the accompanying drawings; and itconsists ofthe novel devices and combination ofdevices herein-A after described, and defined in the claims.

This invention has for its principal objects, rst, to provide a firmer connection between the so-called I-beams and the tile-blocks, and, second, to improve the construction of the joints or connections between the abutting or overlapping beams.

In the drawings like characters indicate like parts throughout the several views.

Figure 1 is a perspective view with parts broken away, showing the manner in which the I-beams are connected at the corner formed by four connected bins. Fig. 2 is a plan view of the same construction as that shown in Fig. 1, but showing tile-blocks in working position. Fig. 3 is a transverse vertical section on the line w3 x3 of Fig. 2. Fig. 4 is a plan view illustrating the manner in which the I-beams are connected at the junction of two abutting bins. Fig. 5 is a vertical section on the line x5 of Fig. 4. Fig. 6 is a plan view illustrating the manner in which the I-beams are connected at the exposed corner of a bin. Fig. 7 is a vertical section on the line @ci :ri of Fig. 6. Fig. 8 is a vertical section on the line 008 w8 of Fig. 6. Fig. 9 is a view corresponding to Fig. 1, but illustrating a slightly-modified construction. Fig. 10 is a plan view corresponding to Fig. 4, but illustrating a slightly-modified` construction. Fig. 11 is a View corresponding to Fig. 6, but illustrating a somewhat-modified construction; and Fig. 12 is a view corresponding to Fig. 8, but illustrating a slightly-modified construction.

In my present invention, as in my identilied prior application, the bins are of rectangular form and are made up of layers of tiling, between which horizontally extended Ibeams are placed to hold the said blocks in position and to strengthen the structure. Also these so-called I-beams are perferably formed by channel-beams placed back to back and secured in any of a great many different ways.

In my presentconstruction as an improvement over the construction of said earlier application the fianges of the I-beams are bent or turned inward, so as to afford a dovetailed channel or groove. The edges of the tileblocks being placed in these dovetailed grooves and the said grooves being filled with cement there is formed when the cement hardens a dovetailed connection or joint between the I-beams and the said tile-blocks. In this way the component parts of the bins are more securely bound together.

In the drawings the tile-blocks are indicated by the numeral 1, while the I-beams, which are made up of channel-beams 2,placed back `to back, are provided with inturned t ilanges 2a.

(See Figs. l to 8, inclusive.) At the corners of the bins the adjacent cavities of the tile-blocks l are iilled with cement, as indicated at 3, and in line with these filled compartments heavy anchor-pins 4 are passed through the I-beams 2 2, as best shown in Figs. 5 and 8, but also in the other views. T o form a support for the cement 3a, which is contained between the downturned iianges of the I- beams, (see particularly Fig. 3,) thin strips of metal or other suitable material 5 are placed on the tops of the tile-blocks 1, and preferably a thin layer of cement 3" is spread between the said tiles and plates 5.

3C indicates the cement, which is placed in the dovetailed channels formed on the upper surfaces of the I-beams. y.

In the construction illustrated inFig. 12 the so-called I-beams are provided with curved fianges 2b, and the bodies ot' the channel-beams 2, which form the said I-beams, are shown as slightly separated at 2c by cement. Furthermore, the eXtreme edges of the flanges 2" are turned radially inward, as

ICO

shown at 2d, and these edges are embedded in the cement contained within the curved flanges 2b. It may be here stated that the expressions I -bearns7 and dovetailed joints7 are used in a very broad sense.

In my present invention the I-beams are overlapped at the corners of the bins, so that independent joint-plates are not necessary. In the construction illustrated in Fig. 1 the under members ofthe channel-beams 2,which make up the I-beams, are shown as cut off at their meeting edges. The flanges of the upper channel--beams 2 are cut olf on vertical lines with the underlying ends of the lower channel-beams 2; but the bodies or fiat portions of the said upper channel-beams are extended and overlapped, as shown at d. It desired, the under channel members 2 might be overlapped in the same manner as are the upper members.

In Fig. 4 the two I-beams which stand in line are connected the same as in the construction illustrated in Figs. l and 2; but the third and transversely-eXtended I-beainthat is, the upper channel member thereofisprovided with a long dat body extension a2, which is passed iirst between the overlapped ends of the other two I-beams and is then bent inward and over the top of the same.

In the joint illustrated in Figs. 6 and 7, which joint is supposed to be located at the outer cornerot the corner-bin, the lower channel members 2 are cut off, as before, and so, also,are the flanges of the upper channel members; but the flat body portions of the said upper channel members are overlapped and crossed and are then folded backward, the one upward and the other downward, over the sections which they embrace. In this way the I-beams are rigidly interlocked at their corners.

In the construction illustrated in Figs. 9 to 1l, inclusive, channel or I beams of different widths are employed, and these are overlapped telescopically without requiring the flanges of the said beams to be cut olf.

In Fig. 9, which corresponds to Figs. l and 2, two of the alined upper channel members 2 are overlapped, the one extending within the other, while the upper channel members V2, which extend at a right angle thereto, are cut o and simply abut against the flanges of the wider of the two overlapped channel members. The arrangement of the under channel members is substantially the same as that of the upper, except that the overlapped under members extend at a right angle to the overlapped upper members. This, as is obvious, gives a very rigid joint.

The construction illustrated in Fig. l0, which corresponds in location to Fig. 4, is very much the same as that illustrated in Fig. 9, but in this case one of the four radiating I-beams is dispensed with. Again, in the construction illustrated in Fig. l1 the construction is the same as that illustrated in Fig. 10, With theomission of those portions which in Fig. 10 project toward the right.

From the foregoing description it is evident that my invention above described is capable of quite a large range of modification.A Y Y WhatI claim, and desire to secure by Letters Patent of the United States, is as follows:

l. A bin or similar structure, made up of layers of tile-blocks and flanged metal beams connected by interlocking dovetailed joints, substantially as described.

2. A bin or similar structure, made up of layers of tile-blocks and interposed horizontally-extended metal beams, having inturned fianges,'said blocks and beams being interlocked by cement applied in the channels of said beams, substantially as described.

A bin or similar structure made up of tile-blocks and horizontally-extended interposed I-beams, the flanges of which Ibeams are turned inward to form dovetailed channels for receiving the edges of the tile-blocks, and cement placed within the dovetailed channels of said I-beams and interlocking the same with said tile-blocks, substantially as described.

4. A bin or similar structure, made up of alternatelayers of tile-blocks and interposed I-beams, which I-beams are afforded by channel-beams laid back to back and provided with inturned flanges, anchor-bolts passed through the said channel-beams, and cement placed within the channels of the said beams and' interlocking the same with said tileblocks, substantially as described.

5. A bin or similar structure comprising the tile-blocks 1, the channel-beams 2 placed back to back to form I-beams and provided with the inturned flanges, the cement-supporting plates 5 on the upper edges of the tile-blocks, and cement placed in the chfan.-`

nels of said I-beams and interlocking the same with said tile-blocks, substantially as described. lf

6. In a bin structure ofV the character described, the combination with successive layers of tile-blocks or similar material, of interposed flanged metal beams, "which beams at the corners of the bins are overlapped and folded back one over the other, substantially as described.

7. In a bin structure of the character described, the combination with successive layers of tile-blocks or similar material, of interposed I-beams, connected at the corners ofthe bin, by overlapped and overturned body portions, the lianges of which beams are cut away at their overlapped portions, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
